Variations of Undrained Shear Strength of EPB Mud and a Calculation Model Based on Consistency Index

Advances in Civil Engineering
If earth pressure balance (EPB) shields are used for tunneling in clayey soils, dispersants are often applied to condition the mud. For the conditioned mud, the undrained shear strength is a key indicator determining the shield tunneling operational ...

Undrained Shear Strength of Unsaturated Soils under Zero or Low Confining Pressures in the Vadose Zone

Vadose Zone Journal, 2018
In geotechnical engineering practice, many projects such as stability analysis of slopes or trenches and pavement design involve soils in vadose zones at shallow depths, where soils are under unsaturated conditions. For these types of projects, undrained

Interpreting Non‐Linear Compaction Mechanics of Expansive Soils Using Reliability Calibrated Framework

Applied Research, Volume 5, Issue 5, October 2026.
This study introduces a reliability‐calibrated machine learning framework to predict the maximum dry density and optimum moisture content of heterogeneous soils. By integrating 15 algorithms with conformal prediction, the models deliver accurate compaction estimates alongside rigorous, distribution‐free 90% confidence intervals.

Time‐Dependent Settlement Model for Driven Piles Using Hybrid Finite Element‐Artificial Neural Network and Regression Approaches

Engineering Reports, Volume 8, Issue 9, September 2026.
This study investigates time‐dependent settlement of pile foundations. A hybrid framework combining Artificial Neural Networks and Finite Element Modeling was developed to derive an empirical equation for the pile‐soil system stiffness evolution over time. The model was validated and calibrated using laboratory test data.

Undrained shear strength of the heavily consolidated clay

Annals of Warsaw University of Life Sciences - SGGW. Land Reclamation, 2013
Abstract Undrained shear strength of the heavily consolidated clay. The undrained shear strength (cu) is considered one of the most basic parameter characterizing soils in engineering practice. The particular importance of cu is in the case of clayey soil. This parameter also is the basis for the classification of soil according to the ISO standard.

Laboratory Study on Vallejo and Scovazzo’s Methods in Estimating the Rheology Parameters of Bentonite and Kaolinite Muds

Civil Engineering Dimension
The mud undrained shear strength and viscosity are the essential parameters in understanding the behavior of mudflow. One of the laboratory test methods to estimate the undrained shear strength and viscosity is Vallejo and Scovazzo’s cylinder strength ...

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 13, Page 5068-5091, September 2026.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Undrained shear strength of Lisbon Miocene clay: a reappraisal based on triaxial and pressuremeter test results

SN Applied Sciences, 2021
Undrained shear strength plays a fundamental role on the behaviour of clays. In overconsolidated clays, this parameter is largely influenced by test conditions, namely consolidation stress.

A fully coupled dynamic poroelastic analysis for partially saturated soils incorporating inertial effects under transient stress loading

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract An accurate characterization of transient interactions between interstitial fluid flow and solid matrix deformation under dynamic stress loading is essential for understanding the poroelastic response of unconsolidated, fluid‐bearing sedimentary deposits.

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.
